The question asks: A ______________ consists of people who choose themselves to be part of the sample by responding to a broad appeal.

Since the answer options are not provided in the data, I will proceed by explaining the concept that completes the blank and then briefly contrast it with common alternatives.

Explanation of the correct concept:
- A voluntary response sample is formed when individuals self-select into the sample by responding to a call or invitation. People who feel strongly about a topic are more likely to respond, which is why this sampling method is prone to bias.
- This type of sample is driven by self-selection, where participation depends on the individual's willingness to respond after a broad appeal or invitation (e.g., online polls, call-in shows).

Why this is correct for the blank:
- The phrasing “choose themselves to be part of the sample by responding to a broad appeal” directly describes self-selection, which is the hallmark of voluntary response samples.

Potential misconceptions if options were present:
- If a choice described a convenience sample, it would be about individuals who are readily available, not necessarily those who actively self-select in response to a broad appeal.
- A simple random sample would involve random selection from the entire population, with no self-selection, which is the opposite of voluntary response behavior.
- A systematic sample involves selecting every kth member from a list, which again is not based on self-selection or broad call-to-action.
- A stratified sample would involve dividing the population into strata and sampling from each, not self-selection in response to a broad appeal.

In summary, the term that best fits the described process—self-selection in response to a broad appeal—is voluntary response sample, reflecting a sampling method often criticized for high nonresponse and voluntary response bias.
